This survey revisits the research in Germany in the seventies and eigh
ties on carburization conducted in a Fine cooperation of research inst
itutes and a supplier of high temperature alloys, funded in the progra
mme FEKKS by the BMFT. The kinetics and mechanism of the carburization
of high alloy Cr-Ni-steels and the main reasons for failure were eluc
idated, also ways and means for corrosion protection and avoidance wer
e developed.
